# State Engine Core-boundary readiness addendum v1

Status: **K1-K3 readiness addendum to the frozen TP8 v1 boundary**

The TP8 [`state-engine-core-boundary-v1.md`](state-engine-core-boundary-v1.md) is a hashed input to
the frozen K1-K3 audit and therefore remains byte-for-byte unchanged. This addendum records only the
classification delta established by the subsequent
[`state-engine-k1-k3-readiness-v1.md`](../evidence/state-engine-k1-k3-readiness-v1.md) evidence.

## Classification delta

| Component | Current classification | Readiness decision |
|---|---|---|
| Frozen repeated transition/challenge/review/calibration evaluation | supported acceptance surface | K2 is ready for the named bounded single-node capability after 40/40 exact cases and replays, 35 required abstentions, five predeclared calibrations, and zero unsupported acceptances, provenance failures, isolation leaks, or provider use |
| Bounded fresh-process task, rollout, promotion, reconciliation, later-use, correction, and retrieval orchestration | supported acceptance surface | K3 is ready for the named bounded single-node capability after 5/5 repeated database/API/worker/thin-client journeys with zero failures, retries, degraded states, isolation leaks, simulation-as-observation rows, or provider use |
| Automated transition discovery, broad-domain calibration, and real-world causal/forecast accuracy | experimental Core capability | unchanged; K2 readiness does not establish any of these claims |
| Full-monolith, hosted, distributed, multi-writer, deployment, and release operation | deferred / unmeasured | unchanged; the bounded K3 API mounted the production task, extension-invocation, intelligence, and capture routers plus the ordinary worker and unchanged client, not unrelated monolith subsystems |

The acceptance thresholds and receipts remain versioned evaluation policy, not a new public runtime
API. The stable semantic contracts, extension ownership, exact eleven-tool boundary, schema head,
and compatibility guarantees in the frozen TP8 boundary remain unchanged.

## Retained-store preparation finding

The TP8 retained benchmark store is evidence input, not a deployable full-runtime database image.
The readiness audit found its selectively applied State Engine v168 planes alongside a stale schema
receipt and missing base-runtime tables. Only a disposable clone was completed for the bounded K3
process audit. Operators must continue to use the supported schema-zero or documented upgrade path
for a full runtime.

## Remaining limits

K2/K3 readiness does not establish real-world calibration, beneficial impact, general learned world
model behavior, autonomous improvement, or distributed guarantees. Provider-backed latency and cost
remain governed by ordinary ACE task budgets because the readiness audit was explicitly
provider-free. R7 is unblocked but was not started; L1, T1, B1, E1, deployment, and release readiness
remain unchanged.
